I To all whom it may) concern:

application to this Be it known that I, ALVA J- FISHER,

citizen ofthe United States, residing Evanston, Cook county, Illinois, have nvented certain new. and useful Improvements .in Agitating' Mechanism, Of'WhlCh the following is a specification.

My invention relates to agitating mechanism that may have'a variety of applications or uses such as for washing machines, churns, ice cream freezers, and so forth.

The object of my invention is to provide novel, efficient and; reliable mechanism of this character and one moreover which s compactand economical of manufacture.

By tion from any source of power such as an electric motor or gasolene engine is. transformed into the desired oscillatingmotlon for agitating purposes.

Other novel and advantageous features of construction and operation will be apparent from the description hereinafterlgiven.

In the drawings Figure 1 is a sectional elevation of my device or mechanism illus- -'trated in connection with one specific use.

or application such as a washing machine, a portion of which is shown; Fig.2 another side elevation of such mechanism; Fig. 3 a sectional plan view on the line 33 of Fig. 1; Fig. 4 a section on the line 4-4 of Fig. 2 and Fig. 5 an elevation of the parts illustrated in Fig. 4.

While as hereinbefore stated my invenof applications or tion may have avariety ofa clear disclothis frame or plate in the bearing 4 is mounted a main shaft 4 tov which is secured 'a pulley 5 driven by means of the belt 6 from a. small pulley 7 on the armature 8 of an electric motor 9 which is herein shown as the prime mover although any other source of power may be utilized. To this shaft is secured a pinion 10 meshing with 3 Specification of Letters Patent.

a large gear secured to a shaft 12 which is ournaled -1n the bearings 13 onthe plate -or frame 1; This gear is provided on'one side with a crank arm 14 which is pivotally connected by meansof a link 15 with a reciprocating rack bar 16. As shown more particularly in Fig. 2 this bar has at one.

end a depending and offset portion'16 to .whose lower end the outer endof the link 15 is pivotally connected. V This bar is adapted to reciprocate or slide inpostsor standards 17.18 rising vertically from the base plate orframe and preferably forming an integral part thereof. These standards are slotted to form guideways for the bar and in order to reduce the friction of reciprocation to a. minimum such guideways are provided with small anti-friction rollers 19.adapted to bear on the top and bottom respectively of the rack bar as clearly indicated in Figs. 2, 4 and 5, it being-understood .that only the standard 17 is so equipped with these rollers although if desired the other standard 18 may be similarly equipped. Furthermore these rollers which are mounted upon short pins or shafts 20 which passthrough the vertical slots 21 of the standards are adjustable vertically, the same being held in any desired adjusted .position by means of the nuts 22.

v The bar 16 is provided at its free end with the rack 16 preferably formed integral therewith with the teeth arranged in a vertical plane and in position to mesh with the pinion 23. This pinion is secured to a ver-.

'ticalshaft or rod 24 which is directly secured tot-heagitating device of the washing machine in the presentiinstance.

From the foregoing description it will be understood that the rotary movement transmitted from the electric motor is translated into a reciprocating movement of the pinion 23 and its rod or shaft 24, which, it will be-understood, may be adapted to any sort of agitating device according to the particular application or use to which my. agitating mechanism is applied. This rotary movement is transmitted from the large pulley 5 to its pinion 10 and thence to the large gear 11. This movementis thereupon transmitted through the connecting rod 15 to the rack bar 16 which is caused to reciprocate in the guides or standards 17 and 18. This reciprocating movement of the rack bar is thereupon transmitted from the rack 16" to the pinion; 23 which given an oscillating movement. mechanism which is not onl simple in construction and economical of manufacture but also compact, efficient and reliable in actual use. 1
